Claude Code 2.1.84 डाउनलोड करा

- Added PowerShell tool for Windows as an opt-in preview. Learn more at https://code.claude.com/docs/en/tools-reference#powershell-tool
- Added ANTHROPIC_DEFAULT_{OPUS,SONNET,HAIKU}_MODEL_SUPPORTS env vars to override effort/thinking capability detection for pinned default models for 3p (Bedrock, Vertex, Foundry), and _MODEL_NAME/_DESCRIPTION to customize the /model picker label
- Added CLAUDE_STREAM_IDLE_TIMEOUT_MS env var to configure the streaming idle watchdog threshold (default 90s)
- Added TaskCreated hook that fires when a task is created via TaskCreate
- Added WorktreeCreate hook support for type: "http" — return the created worktree path via hookSpecificOutput.worktreePath in the response JSON
- Added allowedChannelPlugins managed setting for team/enterprise admins to define a channel plugin allowlist
- Added x-client-request-id header to API requests for debugging timeouts
- Added idle-return prompt that nudges users returning after 75+ minutes to /clear, reducing unnecessary token re-caching on stale sessions
- Deep links (claude-cli://) now open in your preferred terminal instead of whichever terminal happens to be first in the detection list
- Rules and skills paths: frontmatter now accepts a YAML list of globs
- MCP tool descriptions and server instructions are now capped at 2KB to prevent OpenAPI-generated servers from bloating context
- MCP servers configured both locally and via claude.ai connectors are now deduplicated — the local config wins
- Background bash tasks that appear stuck on an interactive prompt now surface a notification after ~45 seconds
- Token counts ≥1M now display as "1.5m" instead of "1512.6k"
- Global system-prompt caching now works when ToolSearch is enabled, including for users with MCP tools configured
- Fixed voice push-to-talk: holding the voice key no longer leaks characters into the text input, and transcripts now insert at the correct position
- Fixed up/down arrow keys being unresponsive when a footer item is focused
- Fixed Ctrl+U (kill-to-line-start) being a no-op at line boundaries in multiline input, so repeated Ctrl+U now clears across lines
- Fixed null-unbinding a default chord binding (e.g. "ctrl+x ctrl+k": null) still entering chord-wait mode instead of freeing the prefix key
- Fixed mouse events inserting literal "mouse" text into transcript search input
- Fixed workflow subagents failing with API 400 when the outer session uses --json-schema and the subagent also specifies a schema
- Fixed missing background color behind certain emoji in user message bubbles on some terminals
- Fixed the "allow Claude to edit its own settings for this session" permission option not sticking for users with Edit(.claude) allow rules
- Fixed a hang when generating attachment snippets for large edited files
- Fixed MCP tool/resource cache leak on server reconnect
- Fixed a startup performance issue where partial clone repositories (Scalar/GVFS) triggered mass blob downloads
- Fixed native terminal cursor not tracking the text input caret, so IME composition (CJK input) now renders inline and screen readers can follow the input position
- Fixed spurious "Not logged in" errors on macOS caused by transient keychain read failures
- Fixed cold-start race where core tools could be deferred without their bypass active, causing Edit/Write to fail with InputValidationError on typed parameters
- Improved detection for dangerous removals of Windows drive roots (C:\, C:\Windows, etc.)
- Improved interactive startup by ~30ms by running setup() in parallel with slash command and agent loading
- Improved startup for claude "prompt" with MCP servers — the REPL now renders immediately instead of blocking until all servers connect
- Improved Remote Control to show a specific reason when blocked instead of a generic "not yet enabled" message
- Improved p90 prompt cache rate
- Reduced scroll-to-top resets in long sessions by making the message window immune to compaction and grouping changes
- Reduced terminal flickering when animated tool progress scrolls above the viewport
- Changed issue/PR references to only become clickable links when written as owner/repo#123 — bare #123 is no longer auto-linked
- Slash commands unavailable for the current auth setup (/voice, /mobile, /chrome, /upgrade, etc.) are now hidden instead of shown
- [VSCode] Added rate limit warning banner with usage percentage and reset time
- Stats screenshot (Ctrl+S in /stats) now works in all builds and is 16× faster
